Hagryphus (meaning "Ha's griffin") is a monospecific genus of caenagnathid dinosaur from southern Utah that lived during the Late Cretaceous (upper Campanian stage, 75.95 Ma) in what is now the Kaiparowits Formation of the Grand Staircase–Escalante National Monument. [1]
The bones of the skull roof were fused and by a folding of the frontal bones, a "double" skull roof was created. In Triceratops, some specimens show a fontanelle, an opening in the upper roof layer. The cavity between the layers invaded the bone cores of the brow horns. [30] Back of skull, showing rounded joint which connected the head and neck
It is composed of 270 bones at the time of birth, [2] but later decreases to 206: 80 bones in the axial skeleton and 126 bones in the appendicular skeleton. 172 of 206 bones are part of a pair and the remaining 34 are unpaired. [3] Many small accessory bones, such as sesamoid bones, are not included in this.
The researchers named the leopard-size species Bastetodon syrtos as a nod to the cat-headed ancient Egyptian goddess Bastet because of the species’ unique shorter snout compared with other ...
Various carnivorans, with feliforms to the left, and caniforms to the right. Carnivora is an order of placental mammals that have specialized in primarily eating flesh. Members of this order are called carnivorans, or colloquially carnivores, though the term more properly refers to any meat-eating organisms, and some carnivoran species are omnivores or herbivores.
The parietal bones did not project past the squamosals and had V-shaped hind margins, with emargination (a series of notches) spanning their entire width. [2] [7] Diagram showing the skull from above and the left side. The epiossifications on the squamosal bones of Kosmoceratops became progressively larger towards the back of the neck frill ...
The neck frills of ceratopsids are surrounded by the epoccipital bones. [ 9 ] : 66 The name is a misnomer, as they are not associated with the occipital bone . [ citation needed ] Epoccipitals begin as separate bones that fuse during the animal's growth to either the squamosal or parietal bones that make up the base of the frill.
Skeletons of a human and an elephant. Comparative foot morphology involves comparing the form of distal limb structures of a variety of terrestrial vertebrates.Understanding the role that the foot plays for each type of organism must take account of the differences in body type, foot shape, arrangement of structures, loading conditions and other variables.
